I didn't like it either but if Rogue can be married to Magneto...
Yes, he did. And it didn't make sense to me but Marvel had Kurts romantic life in full throttle: His dance with Storm, his kiss with Rachel, the flirting with Betsy, dating Night Nurse... Maybe it was to make up for his time as a priest.
Rachel putting this sex pest in his place. I think Nigel became Satyre-9's slave later.
